Evolved high-technology reverb plugin

atomicreverb is a modern and innovative algorithmic room- and reverb plugin for common interfaces like VST 2, VST 3 and AudioUnits.

With a unique, sophisticated algorithm design, atomicreverb provides users all possibilities to create stunning dense, smooth and natural reverb acoustic patterns with a high degree of customization.

Ambiences, Halls, Rooms, Plates, Chambers, Stages, Tubes, ...

atomicreverb comes with a huge set of 240 predefined factory presets which are intuitively modifiable to support the maximum productivity for designing breathtaking sound.

Highly configurable processing for both early-reflections and late-reverb/tail provides a maximum flexibility through- out the entire spectrum.

This dramatically enhances the sonic range to produce sounds from subtle voice reverbs over impressive rooms to full and dense halls or even tubes, stages, plates or special-FX.

For early-reflections - the most important part to describe the sound of the 'room' and create nice short ambiences - atomicreverb supports a set of over 170 different predefined early-reflection signatures (extracted from real room impulse-responses), which are additionally changeable in size, hardness, resonance and spreading/diffusion.

And to add more creative freedom, different algorithms for late-reverb ('reverb-tail'), interesting wall- absorption effects, complex modulations and even gated tail length (used for percussive sounds) are provided.



"I'm very impressed with Atomic Reverb. It became my default verb for
most things in just under an hour after installing."
(atomicReverb User)

High quality and precision

To keep the highest quality, atomicreverb use an internal 64bit signal processing with optional 2x oversampling and high degree sample interpolation. Reverb tails beyond minutes will be as accurate as possible.

Realistic, not static

atomicreverb does not use static models like convolution or impulse-response related reverb plugin effects. Every process renders reflections like in the reality - with all its characteristics and dynamics. Simulated moving airflow realized by complex modulations will also add deep, breezy and individual reverb-tails for every instance.

High performance

Because different presets need different calculation details, a preset additionally stores the degree of detail - and thus optimizes the needed CPU load. High performance algorithms allows to run more than 100 plug-in instances, depending on your CPU.

And even more..

atomicreverb supports even common parameters like room-size, room-width, stereo-position, different damping parameters and a 5-channel EQ with spectrum-analyzer to design individual sound colors. Parameters like dry/wet, gain and density can be locked from changes when selecting other presets.

The A/B program comparison, and preset copy & paste and UNDO/REDO simplifies preset creation. Presets can also be imported and exported via the system's clipboard using XML-text for easy sharing.



Using the integrated MIDI-learn function, parameters can be assigned to MIDI controllers via your host-software.

atomicreverb also supports an arbitrary scalable/resizable user-interface and two different skins.

Standalone application (Windows)

For Windows-Systems a standalone application is included to use atomicreverb directly as a reverb-effect through your audio-hardware. An easy way to use reverb for your live-performance!

"...what MolecularBytes has delivered here is pure quality - the sound is natural and warm, the user-interface simple and logic. The huge preset-collection is extremely useful in many recording situations. And above all, the price of 69,- Euro is more than fair [...] From now on AtomicReverb will also be used in our studio."

The German pro music magazine KEYS tested atomicreverb in issue May/16:

" eye-level with the upper-class [...] Atomic Reverb is an excellent reverb plug-in and convinces."


"Atomic Reverb has a soul and musical quality that I can't get elsewhere. Love the 'Philharmonic Hall' and 'Taj Mahal' presets, some of the warmest and lush sounding soft reverb."
